In order more clearty to explain the ep erati on of the newwan angeme'nt it will be fillet assumed that the tube 1' does ep erateand: that no oscitlationsare: neceived by the control-ling tube 5. Under, these conditions: the elay 9 is traversed by a eertwin current. It will close the contacted its" armature, whereupon the rel-37y M he" comes energizedpand the eontaiet 15 is opened. The resistance 10 is now included in the circuit weak'e'ningthe cur re'nt'. The Contact 1?- is opened, whereupon the contact 15 closes and the cycle ofiopemtion 13$ gins over-again Thetwo relays Skaimi 14 operate as a vibrator.- J

Ifwe assn me now that the tube 1 is-efiergized and maintainspthe oscil latin'gi condition in the circuit 2 the ooil 45-, which is assoeiated with this circuitwill take up a centain energy, which produces 'citculation oi? rectified cement in the circuit 4; 10, 9, 5; the: apparatus is so) constructed and tidjnstedthat the intensity of this eminent is suflicicnt for holding the contact-of relay 9' imfel-osed position; Under? these eondt tions, all of the heating resistance of the thermestat, i, e;,vthe two peztions 10 2116 11 heating resistance of the thermostat is in the batterycircuita At the same time the oscillating order returns from circuit 3 to circuit 2. If at this time the signal still exists, the same cycle is reproduced. For operating a call this is carried on in such a manner that during the reception of a signal the group of two relays is in vibrating condition and the energy transmitted into heat in the thermostat oscillates between two values, one

corresponding to the normal conditions and the other in which R designates the resistance of por tion 16 and R the-resistance of portion 10. The contact of the thermostat is adjusted in a manner such that a thermic balance is established so that the contact is made when the relays '9 and 14 are in normal condition as a result of the energization of relay 9, and the thermic balance is not reached before this contact is made when the relay vibrates. The duration of the vibration, i. e. a duration that the signal must have for causing the operation of the calling device 12, is adjustable by the spacing of the thermostat contact and depends also on the construction of this apparatus. It will be seen that these adjustments may be easily effected or the construction standard determined irrespective of the reception of a signal, simply b stopping the operation of the tube 1. Uiider normal conditions, if either tube is damaged the callingapparat-us will immediately give the signal as the relay 9 willthen be deenergized. I

Obviously, numerous modifications of the above described arrangement are possible without departing from the spirit of the invention. The relays 9 and 15 may be of any suitable type that will perform the above described operation, or these relays may even be replaced by a single relay provided with suitable self-interrupting contacts. Furthermore, the thermostat or thermo-interrupter may perform other well known functions, only the division of its heating winding being a characteristic of the invention.
